Application filed September 20, 1911. Serial.- iNo. 650,471.

To all fra/wm muy concern Bc it. known that we, SAMUEL K. Srinonn, Jr., and HARRY l. ROBINSON, both citizens of the `United States, residing at the city ot Philadelphia, in the county of, Philadelphia and State of Pennsylvania, have invented course of the .car at turnouts, without havr ing to stop the saine.

rthe nat-ure and scope otl our present invention will be'niore fully understood from the following description taken in connection with the accompanying drawings forniing part hereof, in which,

Figure l, is a top or plan view of a section ot a road-bed showing a crossing and turnout having a shiittable switch and electrical means manually actuated from thel car by a motornian to shift the switch, einbodying main features ot' our present invention. Fig. 2, is an enlarged transverse sectional. view on the` line fr, m, ot Fig. l, and showing in broken section the car platform, the spring controlled contact disks and the electro-magnets and armatures for cont-rolling shiftings of the switch trom the car by the motoriiian; and Fig. 3, is a diagram, showing the arrangement of theswitch circuits in'v a branch of the controller' car circuit, and the switch and mechanical parts to permit of shifting the course of a car, without stopping the same.

Referring to the drawings al and a2, are track-rails mounted on a road-bed a.

ac3, is a. crossing having a turnout pro vided with an ordinary tongue-switch at.

'b and b1, are current distributing rails located inside ot' the track-rails.

b2, represents the platform ot the ci Depending therefrom and secured thereto, are U-shapcd brackets la and /c, 'in which brackets are mounted spring controlled ver-l tical ootplungcrs bt and b, having at their lowered ends contact disks o and b". These disks, by depressing either of thesaid plungers are adapted to make sliding Vcontact with the cont-act rail I) or 51, located between the track-rails al and a2, to energize an clectro-iiiagnet and thereby. shift the switch-tongue c4. On the oot-plungersfb4 and b", are secured stops bs, and b9, within and beneath the supporting brackets i: and f, tor the springs 61' and bu7 surrounding said toot-p1ungers, as clearly shown in Fig. 2, in orderthereby to limit the extent ot movement of the said 'foot-plungers.' l v Z and (Z1, are the electro-magnets located in a concrete or similar casing d2, underneath the road-bed a, as clearly shown in Fig. 1.

d, is a lever-arm suspended `from the switch-tongue and carrying armatures Z4 and d, for the electro-magnets l and d.

When either footsplunger b or if', is depressed under the tension ot the springs blo and b, coiled around the same, a contact disk Il or 07,' will inakc contact4 with the l current distributing rail Z or b1, and a current will pass through one ot' said electromagnets d aiid (Z1, to thus cause the switchr` tongue a", to be shifted into required position to permit the carto pursue its regular course beyond the turnout, or to pass around the turnout of the cross-over section of the road-bed, without. having to stop the car.

In Fig. 3, in diagram, is shown the overhead trolley line 5, which by a pole and line (5, is connected to a circuit breaker li, of the carb?, thence by the line 7, controller 8, and

line t), to one brush c, ot the motor- E, and thence by the other brush el, of the'rnotor E, and line l0, to ground g. The line Gis shuntod from the circuit breaker i, by the lines 12, 12*L and 12b, to the tootplunge|rs b4 and b5. The current distributing rails and b1, by the lines 1,3 and 14, are connected to the electromagnets d and (il, and the-circuit therefrom 'is continued to either ground g1 or g2. When the toot-plunger b, as indicated in dotted outline in Fig. 2, is pressed into ycontact with the rail b1, the current from the main line 5, through the car is shunted from the circuit breaker la, through the line 12,'withoutaffecting the controller car circuit 8 so as to eneri'ize the' electrov tongue a, to be shifted to the position as 'Y above explained, a similar result, in an opposite position ofthe switch-tongue a4, can be obtainedrtlrus causing the car upon reaching the cross-over to change its course over the road-bed.A

Having thusv described the nature and 0b- '-`\jectof` our invention what we claim as new and desire tvo'r'e by Letters Patent is:-

In combination, tracks having a tongueswitch, two'electro-magnets, a lever-arm located between said magnets andin connection suspended from said switch, the lower end of said lever-arm carrying the armatures of said magnets, an electric circuit, lContact rails located adjacent to said track-rails and included in said circuit, brackets secured to the under sident the car-platform, tootplungers mounted in said brackets and having springs, said foot-plungers provided with stops within and beneath said brackets to control in conjunction with said springs the extent of movement of said foot-plungers and the latter provided with disks adapted to make sliding contact with said contact-rails.

In witness whereof we have hereunto set our signatures in the presence of the two subscribing witnesses hereto.
